数字地图制图中地形图整饰的自动实现

The automatism realization of topographic map decoration in digital mapping

地图整饰是数字地图制图的基本要求,能帮助地图使用者迅速、准确地判读地理信息。以中小比例尺地形图为例,阐述建立地形图数学基础的基本原理,介绍地图整饰中辅助要素的实现方法,总结实现地图整饰的技术思路。通过利用MicroStation软件所提供的二次开发功能,提高地图整饰模块开发的效率。

Topographic map decoration is basic requirements for digital cartography,which can help the user recognize geographic information quickly and perfectly.The basic principles for setting up the mathematical basis of topographic map are analyzed;introduced the method for the realization of accessorial elements;summed up the technical ideas to realize topographic map decoration.Using the secondary function of MicroStation,we improved the efficiency of the module development.
